Title: Formation density measurement utilizing pulsed neutrons
Inventor: ODOM RICHARD C
IPC: G01V5/10
Filed: 1998-01-29
Abstract: A device for measuring the density of a formation uses a high-energy pulsed neutron source which induces gamma rays in the formation, and determines a gamma diffusion length of the formation based on the attenuation of gamma rays produced by inelastic scattering of fast neutrons. The borehole tool houses the neutron source along with a near gamma ray detector and a fan gamma ray detector. The gamma ray detectors are located at different distances from the fast neutron source and spaced sufficiently from the fast neutron source such that dependence of inelastic gamma counts on fast neutron transport and gamma production of the formation is substantially reduced. Gamma ray events can be sorted and counted in time- and energy-dependent bins. The present invention has several advantages over gamma-gamma logging, including deeper penetration of gamma, and is also superior over systems which measure, e.g., hydrogen-based porosity.

Title: Method for continuous production of modified bituminous materials
Inventor: LOPEZ EMILE
IPC: E01C7/26
Filed: 1998-05-14
Abstract: The invention concerns the continuous production of bituminous materials modified by addition of polymers and reacted with sulphur. The binders resulting from said method can contain very high amounts of polymers also combined with secondary materials such as: rubber, various plastics and waste lubricants. This type of binders, which cannot be obtained by discontinuous batch technology, results from the continuous mixing of several bituminous constituents through a static mixer. Said binders provide very high performance bituminous materials and agents for regenerating old bituminous materials contained in waste road materials, in the process of hot recycling of coated materials. They are also used for producing novel emulsions of highly modified binders, with multiple applications and in particular for cold recycling. This novel method, by regeneration of old bitumen contained in waste coated materials, represents a means for waste conversion and for limiting the use of bitumen and road surfacing aggregates.

Title: A method for rendering glyphs using a layout services library
Inventor: BALLARD DEAN D
IPC: G06F17/21
Filed: 1998-06-26
Abstract: Rendering glyphs using a layout services library. A layout services library provides a set of text-processing functions for use by a client program. The text-processing functions access font information stored in the font tables insulating the client program from the details of the font table formats. The layout services library may be used to identify glyph variants and to position glyphs along a base line for a run of text. To identify glyph variants, the layout services library scans the run of text to identify the locations of characters having alternative glyph forms. The layout services library creates a list of feature parameter structures, each of which contains a count of the number of glyph alternates that apply for each identified character. The client program assembles a list of identical characters which have different parameters and presents a list of all glyph variants to the user who chooses one of the alternatives. To position glyphs, the layout services library assembles data that describes the advance of a virtual pen point from glyph to glyph along the base line, an X-placement value, and a Y-placement value. The X-placement value and the Y-placement value are used to position the glyph with respect to the virtual pen point on the base line.

Title: Method and data system for determining financial instruments for use in the funding of a loan
Inventor: BORGERSEN BORGER
IPC: G06Q40/00
Filed: 1998-07-31
Abstract: A method and a computer system for calculating the type, the number and the volume of financial instruments for financing a loan with equivalent proceeds to a debtor, the loan being a loan which has to be partially refinanced during the remaining term to maturity of the loan. The remaining term to maturity of the loan is determined at the beginning of each period such that during the entire term to maturity of the loan, the debtor's repayments are within a band defined by a set of upper and lower limits which may be set for each period, and such that the remaining term to maturity of the loan is also within a band defined by an upper limit and a lower limit. Furthermore, the payments on a special instrument, a repayment guarantee instrument, are determined, said repayment guarantee instrument being designed to ensure that given maximum limits for repayments and term to maturity are observed and supplementing the abovementioned financial instruments. Payments from the repayment guarantee instrument are made in those situations in which the maximum limits for repayments and term to maturity would otherwise have been exceeded. Similarly, payments to the repayment guarantee instrument are made in those situations in which repayments and term to maturity would otherwise have fallen below the minimum limits for repayments and term to maturity. The results of the calculations may be employed by a lender, e.g. a financing institution such as a mortgage credit institution, to ensure that such a loan is financed so that interest rate risks as well as imbalances in payment flows are avoided or minimized.
